Inside ChatGPT: The fastest-growing product in history | Nick Turley (Head of ChatGPT at OpenAI)
In this episode, Lenny sits down with Nick Turley, the Head of ChatGPT at OpenAI, to explore the meteoric rise of one of the most transformative products of the modern era. Recorded just before the launch of GPT-5, the conversation delves into the origins of ChatGPT, the strategic decisions that fueled its rapid growth, and the unique product development philosophy that drives OpenAI’s innovation.
ChatGPT began as a 10-day hackathon project and quickly evolved into a global phenomenon with 700 million weekly users. Nick shares insights into the product’s pricing strategy, which was determined through a Van Westendorp survey in Discord, leading to the now-standard $20/month model. He discusses OpenAI’s philosophy of being 'maximally accelerated,' prioritizing speed without compromising on learning from real-world user feedback. The product’s surprising retention rates—90% after one month and 80% after six—highlight how users return and deepen their engagement over time. Unexpected use cases, from emotional support to relationship advice, underscore ChatGPT’s broad impact. The team also made intentional decisions to ship early, embrace unpolished features, and use TikTok for user research. Looking ahead, Nick reflects on the future of AI interfaces, the importance of evals in product development, and how curiosity and interdisciplinary thinking shape successful product leadership.
